The ships from Andaman to the mainland are available from Kolkata, Chennai, and Visakhapatnam. These are not typical cruise ships that you are used to seeing in movies. They don’t have all the lavish amenities that you are dreaming of. These are actually used to carry basic utilities from the above cities to Andaman. These government-run cargo ships also carry islands’ residents between the mainland and Andaman. Since these are commercial ships, you shouldn’t expect any luxuries you may have seen on private cruises.
